Can I lose money? Is this gambling?
No. There's no wager and nothing at stake. You set a minimum and a maximum, and the reels only ever pick a number between them — so the worst possible spin still leaves a tip you already decided was fair.
Why won't it let me set the minimum below 20%?
That's deliberate. TipSlots is built to make generosity the default, and 20% is the floor by design.
What does the generosity dial actually do?
It changes your odds, not your limits. Turning it up makes the bigger outcomes land more often, but your minimum and maximum never move.
I bought Remove Ads and the banner is still there.
Tap RESTORE PURCHASES in the tip jar. If it's still showing after that, check that you're signed in with the same Apple Account you bought it on, then email me.
I got a new phone — do I have to buy Remove Ads again?
No. Open the tip jar and tap RESTORE PURCHASES.
There's no sound.
Check the silent switch on the side of your phone. TipSlots respects it by design, so it stays quiet when your phone is set to quiet.
The animations are too much.
Turn on Settings → Accessibility → Motion → Reduce Motion. TipSlots respects it throughout — the reels, lights, and celebrations all calm down.
Does it work without internet?
Yes, entirely. Only the ad banner needs a connection.
TipSlots collects nothing. Your bill amounts never leave your phone. Read the full privacy policy →
